options, and illustrated parts lists. The manual is written for NEC-trained customer
engineers, system analysts, service center personnel, and dealers.
The manual is organized as follows:
Section 1 — Technical Information, provides an overview of the system features,
hardware design, interface ports, and internal devices. System specifications are listed,
including dimensions, weight, environment, safety compliance, power consumption, and
memory.
Section 2 — Setup and Operation, includes unpacking, setup, and operation information.
It contains procedures for configuring the system through the Setup utility program and
reinstalling the system software. This section includes procedures for restoring the
operating system, various drivers, and application programs. Information on using the BIOS
Update utility is also included.
Section 3 — Option Installation, provides installation procedures for adding optional
expansion boards, diskette and hard disk storage devices, and system and video memory.
Section 4 — Maintenance and Troubleshooting, provides information on cleaning the
system and identifying system malfunctions.
Section 5 — Repair, includes disassembly procedures along with an exploded view
diagram of the system. Also included are parts lists for field-replaceable parts.
Appendix A — Connector Pin Assignments, provides a list of the system board’s internal
and external connector pin assignments.
Appendix B — System Board Settings, includes information on setting jumpers for
clearing passwords, resetting CMOS, disabling Setup access, and recovering from a
corrupted BIOS.
Appendix C — Hard Disk Specifications, includes specifications for the IDE and SCSI
hard disk drives provided with the computer.

SYSTEM CHASSIS
The chassis provides an enclosure for the system board, power supply, six PCI/ISA
expansion slots, and six storage device slots. The expansion slots include two 8-/16-bit ISA
slots, one shared PCI/ISA slot, and three 32-bit PCI slots. One PCI slot contains either a
Matrox Mystique or a Number Nine Imagine 128 Series 2 video board, depending on the
model.
The six storage device slots accommodate up to four accessible devices and two internal
hard disk drive devices. The accessible devices include the standard one-inch high 3 1/2-
inch 1.44-MB diskette drive and up to three 1.6-inch high 5 1/4-inch storage devices. The
internal device slots support up to two 1-inch high 3 1/2-inch hard disks.
Figure 1-1 shows the front panel features and the locations of the accessible storage device
slots in a system. Figure 1-2 shows the features on the rear panel of the system chassis.

NOTE: The Matrox Mystique video board
installed in some models contains a video module
feature connector, in addition to the standard
VGA connector. The Number Nine Imagine 128
Series 2 video board installed in some models
contains only the standard VGA connector.
